Who has served in multiple branches of the military?

USAF 1983-1987 as an Aeromedical Technician (Flight medic in Barney terms)&nbsp;<div>Army 2009-Present Network Switching Systems Operator, reclassed to SIGINT Analyst</div>

I began my career in the Marine Corps in 1991 as a bulk fueler. I enjoyed my time in the Marine Corps and it was one of the defining moments of my life. But as much as I loved the Corps, I couldn't see myself pumping gas for the next 25-35 years. So I crossed over to the Navy side of the house, serving as an Operations Specialist with detachments for the USS Bristol County and USS Copeland from 1993-1994. I was released into the IRR at the end of 1994 and finished my contract there. I returned to the service joining the Army in 2010 and continue to serve as a medic now. When I leave full time service with the Army I've toyed with the idea of going for a fourth branch and going into the Coast Guard Reserves or Air National Guard. 

USMC 1976-79
US Army 1979-1984

 Don't regret either decision was a couple chapters of my life that will always remain fresh in my mind.

I serve multiple Military Branches:
US Army Active Duty 10/5/1977 -06/02/1986(SSG/E-6)
US Army Reserve Duty: 06/02/1986-06/23/1994(SSG/E-6)
US Navy Reserve Duty: 12/13/2002 - 04/07/2006 (IT1/E-6)
US Air Force Reserve Duty: 02/05/2005 - 06/08/2015 (MSGT/E-7) Retired

I changed from the Navy to the Army. I loved the change.

My 1SG was prior service USMC and was one of the finest leaders I ever knew. He said he learned to lead in the Corps.

I am glad I had the Army experience, but my CG time has been more than I could have hoped for. Glad to be in such great company with all of you multi-service people!
